Nathan Bubna commented on VELOCITY-661:
---------------------------------------
Well, "interpret" is apparently not the clearest of terms, and the docs could
use some improvement (no surprise there). Still, nothing within a #literal
directive is interpreted, in the sense that it is rendered literally, as the
examples show. However, #literal is not a special directive in any sense. The
parser hasn't a clue what #literal intends to do with its content. So,
everything within a #literal block is still parsed.
Like i said, #literal was never designed to prevent parsing of content.
#literal was to make it easy to escape large sections of valid VTL. like most
escaping issues people have with Velocity, they expect to escape invalid VTL,
but all of Velocity's escaping mechanisms (#literal included) were designed to
escape valid VTL only. This is something i think everyone is ready to change
in 2.0, but that doesn't mean it wasn't intentional when it was first done (not
by me, i might add :).
So, to change the #literal directive to make the parser be lenient about its
content, you will have to hardwire knowledge about it into the parser itself.
I'm willing to help commit and test such a solution, but i really don't have
time to develop it myself.

> Key: VELOCITY-661
> URL: https://issues.apache.org/jira/browse/VELOCITY-661
> Project: Velocity
> Issue Type: Improvement
> Components: Engine
> Affects Versions: 1.6.1
> Environment: ALL
> Reporter: ND
>
> I have some velocity templates that include quit some javascript. Inside the
> javascript a javascrip template engine is used which also uses ${varname}
> Escaping each occurance would make the code rather unreable, so to prevent
> velocity from parsing the javascript code, I put a #literal() around it.
> However, velocity still PARSES the contents of this block, which of course
> results in parsing exceptions.
> My feeling with "literal" is that it is completely UNINTERPRETED content?
> This SHOULD work:
> #literal()
> var myId = 'someID';
> $('#test).append($.template('<div id="${myId}"></div>').apply({myId: myId}));
> #end
